- "In gold country, greed is king -- and every road a mine field!"
- — Tagline, from the front cover
Frank, Joe, and Callie are off to Virginia City, Nevada, heart of the Comstock Lode, to visit Callie's friend Kerry Prescott. Kerry's father, Ted, has developed a system to extract new gold from old mines -- but the deeper Ted digs, the more danger he finds. Someone means to put him down for good!
Gold fever is running high, and lives are at stake. But Frank and Joe stake a claim of their own: they're out to put a stop to a gold-digging, gun-toting gang of desperadoes. The Hardys head for a showdown eighty feet underground, where they discover just how wild the Wild West can be.
